I have no idea what's going on with my electrical, I had a optima yellow top and after a year the negative side started getting so much corrosion it ate up the terminal adapter I had on it , the adapter was added because the OEM wouldn't tighten on to the battery post.

DLR on passenger side doesn't work, but on remote start up the passenger side lights up and the driver side blinks/twitches, as soon as I unlock the doors and open the driver side, the light turns on.

I recently got a 5 point inspection but the battery test says failed, replace battery. My bat is almost a month old, $400+ battery.

No corrosion as of now but am worried my lights will stop working on my drive to work at 4 am. I replaced the alternator, had the old OEM alternator checked and it's still on very good shape.

I'm thinking out loud and want to get some ideas before I do anything drastic to the car.
